Description
Technical Field
[0001] The utility model relates to the technical field of brick blank molds, in particular to a mold for changing the stress on the edge of a brick blank and a device for pressing the brick blank. Background Art
[0002] With the development of the ceramic industry, improving product quality and increasing efficiency is an inevitable trend in the development of the industry. Otherwise, products that do not meet the requirements will be gradually eliminated. The flatness of the brick is a process parameter that must be strictly controlled during the production process, which directly affects the use effect of the product. At present, large-tonnage presses are generally used to press the green bricks. The density of the green bricks is relatively uniform, which has little effect on the flatness of the bricks under normal circumstances. However, glazed bricks need to be polished and edged after firing. 8-10mm of scraps are ground off on one side to obtain the finished product (partial enlargement is shown in the attached figure). Figure 4 As shown), by the attached Figure 4 It can be seen that the edge thickness of the glazed finished bricks after edge grinding is basically consistent with the thickness of the whole brick. When two bricks are stacked together, there is almost no gap on the edge. In this way, the center of gravity of the finished bricks is basically evenly distributed in various parts, and the stress is mainly on the edges of the non-fitting parts. When the whole stack is transported and packaged in the later stage, the finished bricks fluctuate due to the bumpy process. There may be collisions between each brick in the whole stack, which is prone to damage such as broken corners or broken edges, and become waste bricks.
[0003] In view of this, the existing technology still needs to be improved and developed. Utility Model Content
[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a mold for changing the stress on the edges of brick blanks and a device for pressing brick blanks, aiming to solve the problem that brick blanks manufactured by existing molds are easily subjected to stress on the corners when stacked after polishing and edge grinding, and the finished bricks fluctuate due to the bumpy process when the whole stack is transported for packaging, and each brick in the whole stack may collide with each other, resulting in chipped corners or broken edges.
[0005] The technical solutions adopted by the present invention to solve the technical problems are as follows:
[0006] A mold for changing the stress on the edge of a brick, comprising:
[0007] template;
[0008] A pressing groove is provided at the bottom of the template;
[0009] a first annular groove, provided on the surface of the pressing groove, for forming a first boss on the bottom surface of the brick;

[0011] Furthermore, the cross-sections of the first annular groove and the second annular groove are both trapezoidal, and the first annular groove and the second annular groove are both square.
[0012] Furthermore, an inclination angle of the inclined surface of the second annular groove on a side close to the first annular groove is smaller than an inclination angle of the inclined surface of the second annular groove on a side away from the first annular groove.
[0013] Furthermore, the first annular groove and the second annular groove have the same depth.
[0014] Furthermore, the depth of the pressed groove is 2-5 mm.
[0015] A device for pressing a brick blank, comprising the mold for changing the stress on the edge of the brick blank as described above, and further comprising:
[0016] Forming board;
[0017] The hydraulic press is arranged on the top of the forming plate; the template is arranged on the bottom of the hydraulic press, and the template corresponds to the forming plate.
[0018] Furthermore, a magnetic suction cup is provided at the bottom of the hydraulic press, and the magnetic suction cup cooperates with the template.
[0019] Furthermore, a positioning groove is provided on the top of the template, and the bottom of the hydraulic press cooperates with the positioning groove.
[0020] Compared with the prior art, the beneficial effects of the present invention are:
[0021] In the present invention, a pressing groove is provided at the bottom of the template for pressing the brick blank, and a first annular groove and a second annular groove are provided on the surface of the pressing groove. The first annular groove is used to generate a first boss on the bottom surface of the brick blank to facilitate the stacking and processing of ceramic tiles, and the second annular groove is used to generate a second boss on the bottom surface of the brick blank to facilitate the stacking and transportation of ceramic tiles. The second annular groove is located inside the first annular groove, and the top of the second annular groove is a plane. By setting the top of the second annular groove as a plane, a trapezoidal boss is formed on the surface of the ceramic tile. After the brick blank is processed and edged, the top surfaces of the two trapezoidal bosses of the two ceramic tiles are abutted against each other, and the corners of the ceramic tiles are spaced apart, thereby preventing the corners from contacting and being easily stressed when the two ceramic tiles are stacked, causing corner or edge collapse.

[0029] In order to make the purpose, technical solution and effect of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0030] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.
[0031] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0032] As attached Figure 1 and attached Figure 4 As shown, the prior art glazed tile template 1 generally includes a first annular groove 3 on the outermost side, and then another bevel groove is provided on the inner wall of the first annular groove 3, so that the finished product produced forms a triangular convex block on its side. Due to the process requirements of glazed tiles, they need to be polished after firing and then edge-grinded. The edge grinding position of the existing brick is between the first annular groove 3 and the bevel groove. Since the bevel of the bevel groove is long and the angle is small, after edge grinding, the edge of the brick layer will be almost unchanged after the upper and lower glazed tiles are stacked. Gaps, so that the center of gravity of the finished bricks is basically evenly dispersed in various parts, and the stress is mainly on the edges of the non-fitting parts. When the whole stack is transported and packed in the later stage, the finished bricks will fluctuate due to the bumps in the process. There may be collisions between each brick in the whole stack, and it is easy to cause damage such as broken corners or broken edges. If the number of damaged bricks 9 is large, in order to reduce the loss of product cost, they need to be turned out manually for cutting and selling. If the bricks 9 have broken edges and corners during transportation and are not discovered and are delivered to customers, it is very easy to cause customer complaints and affect the product brand.
[0033] In view of the shortcomings of the prior art, this embodiment provides a mold for changing the stress on the edge of a brick and a device for pressing a brick. The details can be referred to as follows:
[0034] As attached Figure 2 and attached Figure 3As shown, a mold for changing the stress on the edge of a brick comprises a template 1, a pressing groove 2, a first annular groove 3 and a second annular groove 4; the template 1 can be rectangular or square according to product specifications, the bottom of the template 1 is provided with a pressing groove 2, the pressing groove 2 is formed by the bottom surface of the template 1 being recessed inward, the surface of the pressing groove 2 is provided with a first annular groove 3 and a second annular groove 4, the first annular groove 3 is close to the side wall of the pressing groove 2, and the second annular groove 4 is located inside the first annular groove 3, that is, the first annular groove 3 is arranged around the second annular groove 4, and the first annular groove 3 and the second annular groove 4 are arranged in a circle. The two annular grooves 4 are arranged at intervals, and the top of the second annular groove 4 is a platform; the setting of the first annular groove 3 can form an annular first boss 5 on the bottom surface of the brick 9, and the first boss 5 can facilitate the stacking of two bricks 9; the setting of the second annular groove 4 can form an annular second boss 6 on the bottom surface of the brick 9, and the top of the second boss 6 is a plane, so as to facilitate the stacking of two ceramic tiles after the edge of the first boss 5 is partially ground, and to avoid the contact between the corners of the two ceramic tiles, which can effectively prevent the problem of corner contact and easy stress-induced corner or edge collapse when the two ceramic tiles are stacked.
[0035] During the processing of glazed tiles, polishing is first performed and then edge grinding is performed. The size of the edge grinding is generally 8-10 mm. After edge grinding, the first boss 5 formed by the first annular groove 3 will be completely ground off. In the prior art, the bevel of the triangular convex block of the glazed tiles will also be ground off a part by edge grinding. In the transportation of ceramic tiles, two pieces are generally stacked up and down, that is, the two front faces are facing each other (as shown in the attached figure). Figure 4 As shown in the figure, at this time, the corners of the two ceramic tiles will be close to each other because the edges of the bevel are ground off, and there is almost no gap between the two ceramic tiles, that is, the corners of the two ceramic tiles are in contact with each other, which makes it easy for the ceramic tiles to be stressed during transportation, resulting in corner and edge collapse.
[0036] As attached Figure 2 and attached Figure 5 As shown, the present application forms a platform at the bottom of the pressed brick 9 by setting the bevel groove as the second annular groove 4 and setting a plane on the top of the second annular groove 4. The platform is located on one side of the edging position and will be retained during edging. When two ceramic tiles are stacked relative to each other for transportation, the second bosses 6 of the two ceramic tiles correspond to each other and abut against each other, thereby forming a gap at the corners of the two ceramic tiles, avoiding the corner or edge collapse caused by the contact between the corners of the two ceramic tiles during transportation. At the same time, it can also improve the survival rate and quality rate of the product, further reduce production costs, reduce the labor intensity of employees and reduce the risk of customer complaints.
[0037] In this embodiment, as shown in the attached Figure 3As shown, the cross-sections of the first annular groove 3 and the second annular groove 4 are both trapezoidal; in the pressing groove 2, both side edges of the first annular groove 3 and the second annular groove 4 are inclined, thereby increasing the strength of the first boss 5 and the second boss 6 formed on the bottom surface of the brick 9, as well as the stability of the two bricks 9 when stacked.
[0038] Furthermore, the first annular groove 3 and the second annular groove 4 form an inverted trapezoidal shape in the pressing groove 2, and the bottom surface of the produced brick 9 forms a regular trapezoidal shape; wherein the first annular groove 3 and the second annular groove 4 can also be a right-angled trapezoidal shape.
[0039] In this embodiment, the first annular groove 3 and the second annular groove 4 are square in shape as a whole and are parallel to the four sides of the template 1 , respectively, and a square boss is formed on the bottom surface of the generated brick 9 .
[0040] In this embodiment, the inclination angle of the inclined surface on the side of the second annular groove 4 close to the first annular groove 3 is smaller than the inclination angle of the inclined surface on the side of the second annular groove 4 away from the first annular groove 3. By designing the inclination angle of the inclined surface on the outer side of the second annular groove 4 to be smaller, the length of the inclined surface can be increased to improve the aesthetics of the corners of the ceramic tile.
[0041] Furthermore, the inclined surface of the second annular groove 4 on one side close to the first annular groove 3 can be extended to the side wall position of the first annular groove 3, thereby extending the length of the inclined surface on one side of the brick 9, making it similar to the inclined surface in the prior art to increase its aesthetics. At the same time, a second boss 6 is generated on the bottom surface of the brick 9, so that the two bricks 9 can be stacked on each other and leave a gap at the edge position of the two bricks 9; at the same time, extending the inclined surface of the second boss 6 can also increase the stability of the second boss 6 to avoid breakage or detachment due to collision.
[0042] In this embodiment, the depth of the first annular groove 3 and the second annular groove 4 are the same, thereby ensuring that the height of the first boss 5 and the second boss 6 generated on the bottom surface of the ceramic tile remain consistent; when the ceramic tiles are stacked, the flatness of the two ceramic tiles can be effectively guaranteed, avoiding the ceramic tiles from tilting or one of the bosses not being in contact, resulting in insufficient supporting force.
[0043] In this embodiment, the depth of the pressing groove 2 is 2-5 mm. For ceramic tiles of different thicknesses, pressing grooves 2 of different depths can be selected.
[0044] Furthermore, the distance between the surface of the pressing groove 2 and the top surface of the template 1 is much greater than the depth of the pressing groove 2. By setting the thickness of the template 1 to be larger, it can withstand greater pressure from the press and the reaction force during pressing, and can effectively avoid deformation of the template 1.
[0045] As attached Figure 6As shown, the present application also provides a device for pressing brick blanks, including a mold for changing the stress on the edge of the brick blank as mentioned above, and also including a forming plate 7 and a hydraulic press 8; the forming plate 7 is a flat plate, and its thickness can be selected according to specific requirements. The forming plate 7 is generally placed on a support frame to facilitate cooperation with the template 1, and the forming plate 7 and the template 1 are in a parallel state, so as to maintain the flatness of the brick blank 9; a hydraulic press 8 is provided on the top of the forming plate 7, and the bottom of the hydraulic press 8 is an extended end, and the template 1 is provided at the bottom of the extended end, and the template 1 corresponds to the forming plate 7.
[0046] The pressed material of the ceramic tile can be placed on the forming plate 7 through external auxiliary equipment, and then the hydraulic press 8 is started. The hydraulic press 8 drives the template 1 to descend, and the template 1 is pressed on the pressed material. As the hydraulic press 8 descends, the pressed material forms a brick 9 in the pressing groove 2 of the template 1. After maintaining for a certain period of time, the hydraulic press 8 drives the template 1 to rise, and the brick 9 will be formed on the forming plate 7. Then, the brick 9 on the forming plate 7 is removed by external auxiliary equipment to complete the pressing work.
[0047] In this embodiment, a magnetic suction cup is provided at the bottom of the hydraulic press 8, and the magnetic suction cup cooperates with the template 1; specifically, the template 1 can be made of magnetic material, and when the magnetic suction cup is powered on and started, the template 1 can be adsorbed on the bottom of the hydraulic press 8.
[0048] Furthermore, a positioning groove is provided on the top of the template 1, which is formed by the inward depression of the top surface of the template 1, and the bottom of the hydraulic press 8 cooperates with the positioning groove; specifically, a positioning block can be provided on the bottom of the hydraulic press 8, which cooperates with the positioning groove to avoid the position of the template 1 from being offset, causing the brick 9 to be affected, etc.
[0049] Those skilled in the art will readily conceive of other embodiments of the present invention after considering the specification and practicing the embodiments disclosed herein. This invention is intended to cover any variations, uses, or adaptations of the invention that adhere to the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered as exemplary only; the true scope and spirit of the invention are indicated by the claims.
